Application June 1, 1934, Serial No. 728,578 9 Claims. (01, are-s) The present invention relates to a road sanding machine andhas for its object to provide a truck having incorporated therein means whereby sand may be spread on icy and slippery roads when necessary in a quick and effective manner.

- A further very important object of the invention resides in the provision of a machine of this nature which is positive in its action, reliable in its operation, thoroughly emcient and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in' the combination and arrangement of parts as will hereinafter be more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of a machine embodying the features of my invention.

Figure 2 is a vertical transverse section taken substantially on the line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal section through the bin or body taken substantially on the line 3-3 of Figure 2.

Figure 4 lsa vertical detail section taken substantially on the line 4-4 of Figure 1.

Figure 5 is a horizontal section taken substantially on the line 55' of Figure 3.

Figure 6 is a detail section taken substantially j;

on the line 6-6 of Figure 5.

Figure '7 is a detail section taken substantially on the line 'l--i of Figure 2.' I

Figure 8 is a top plan view of one ing disks.

Figure 9 is a sectional view taken substantially on the line 9-9 of Figure 8.

Figure 10 is a detail sectional view through a clutch hereinafter more fully referred to and Figure 11 is a perspective view of a floor plate for the wagon box.

Referring to the drawings in detail it will be seen that the numeral 5 denotes a truck chassis on the rear portion behind the cab of which is built a box like bin or body 6 with an open bottom and resting on cross beams I. In the front of the of the spreadbin is a trough 8 disposed transversely of the bin being journalled in blocks l2 which are mounted I on rods 84 threaded into sleeves [5 which are embedded in side rails l6 extending along the lower edge portions of the side walls of the bin. The rear wall of the bin has a slot or opening II. An imperforate endless belt I8 is trained over the roller II and the rollers ill, the forwardmost roller I being located immediately above the rear portion of the trough 8. The rods l4 are rotatable through the blocks l2 and terminate at their rear ends in sleeves l9 through which a suitable implement may be inserted to turn the rods for tightening the endless belt 18 when necessary.

On one side of the bin there is provided an elongated longitudinally disposed casing 20 and the shafts of the rollers l0 extend thereinto and on the ends of these shafts are beveled pinions 2| meshing with beveled pinions 22 on a shaft 23 journalled in suitable brackets 24. An auger 25 is located in the upper portion of the trough 8 and is journalled through the sides of the bin as shown clearly in Figure 2 and on the ends of its shaft are beveled pinions 26, 26 meshing with beveled pinions 21, 21 on the upper ends of vertical shafts 28. 28. These shafts 28 are Journalled through hangers 29, 29. Shafts 30 are vertically disposed and journalled through the lower portions of the hangers 29. Gears 3| are fixed to the shafts 30 and mesh with gears 32 on the lower-portions of the shaft 28. On the upper ends of the shafts 39 are formed spreading disks 33 on the upper surfaces of which are centrally located cone shaped humps 34 from which radiate grooves 35. These disks are located immediately below the spouts 9. It is to be noted that the rib 40 on the auger 25 is in two sections starting from the center and reversely spiralled. A sprocket and chain mechanism 4| operatively connects the forwardmost roller l0 with the auger. There is a casing 42 for the gears 26 and 21 on the other side of the bin from the casing 20. A-casing 43 is provided for the gears 3| and 32 under the casing 42 and a casing 44 is provided for the gears 3| and 32 below the casing 20. This casing 44 is best shown in Figure '7 and it will be noted that the shaft 28 which extends into this casing 44 has a beveled pinion 45 thereon meshing with the beveled pinion 46 on shaft 41' journalled in bearing 48. A chain and sprocket mechanism 49 operatively connects the shaft 41 with the drive shaft 50 of the truck.

On the inner lower portions of the side walls are inwardly and downwardly inclined bafiles 50. On the rear wall immediately above the opening or slot I1 is an inwardly and downwardly inclined bafiie below which is a circular antifriction roller 52 above the upper run of the endless belt l8.

With the bin full of sand and the truck moving along the road it will be seen that the endless belt urges the sand forwardly so that it may gravitate into the trough 8 from which it is moved laterally and outwardly to gravitate down the spouts Son to the rotating disks 33 to be scattered and spread on the roadway. Q

Referring again to the chain and sprocket mechanism 69 it will be seen that the same in cludes a clutch mechanism consisting of a gear 5! secured to a suitably mounted stub shaft 52 jo'urnalled in depending brackets 53. The gear 5! is in constant mesh with a pinion gear. 53

provided on the drive shaft to turn with the shaft. One face of the gear 5i is formed as at 54 to provide a clutch element with which is cooperable a clutch element 55 formed integral with one side of the sprocket 49a forming part of the aforementioned chain and sprocket connection '49. The sprocket Ma is formed on the face thereof opposite to the clutch member 55 with a grooved collar 56 with whichis engaged a shifting fork 51. The fork 51 may be operated manually through any suitable mechanism and 'is 'pivotally supported by a suitable bracket 58 as suggested in Figure 2.

In this connection it will be apparent that when the clutch members 54, 55 are disengaged, that is to say, are in the position shown in Figure 10 there will bean interruption of drive between the shafts 50 and 52. However when it is desired to set the parts of the sanding mechanism into operation fork 51 is manipulated to .shift the gear 49a to the left in Figure 10 to engage the clutch members 54, 55. With the clutch members thus engaged drive is transmitted from the shaft 50 to the shaft 52, and from the shaft 52 to the shaft 41 for driving the auger and the spreader disks. It will thus be seen that these will now be quite apparent to those skilled in this art without a more detailed description thereof.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed orsacriflcing any of its advantages.
